Can a patient be enrolled for both shoulders?

No. Patients may only be enrolled in the trial for one shoulder.

• If a patient has MRI-confirmed tears of ≤ 4cm in both shoulders at the time of enrollment, they should be enrolled for the shoulder with the larger tear (unless MD advises otherwise). Treatment for the enrolled shoulder would be randomly assigned. The patient may choose whatever treatment they prefer for the unenrolled shoulder. Treatment does not need to be the same for both shoulders.
• If a patient already enrolled in the ARC trial of one shoulder develops a second tear in the other shoulder, do NOT enroll the patient for the second shoulder. To prevent confusion during follow-up, a patient should only be enrolled in the study for one shoulder.
